SEP-1916 Common Used Sealants
SEP-1916 is a one component silane end-capped polyether sealant, containing no solvent, no isocyanate, no small organic silicon molecule nor polymer.
It's environmental friendly, low VOC, without contaminating substrate. It is cured by absorbing the moisture in the air at room temperature.
Usually not need a primer before apply. It could adapt to thermal expansion and contraction duo to inherent elasticity,
It performs good adhesive to variety of construction materials such as concrete, cement, stone, glass, etc., therefore it could be commonly used.
Characteristics
